Results of my neck MRI
 

I do have neck pain and stiffness, tend to be bad on symptomatic days.

a - Straightening of the cervical lordosis (they say "likely muscle spasm").
I look at the literature on this and find that this is bad from many angles: muscle pain and hampering blood flow to brain. They say this can be treated with PT, Chiro, and Stem cell injections. I also heard that laser helps with muscle recovery and I am going to be trying this at the chiro's/.

b - 6 mm perineural cyst at the C7-T1 level. The clinical significance is not clear. Some say it is possible to cause issues some say no. I am not sure.

Any thoughts?

Perineural cysts, which are also known as Tarlov cysts, are fluid-filled sacs that form on nerves at the base of the spine. A person with such cysts would likely never know it. They almost never cause symptoms. When they do cause symptoms, however, the most common is pain in the lower back, buttocks, and legs

If a C-7 T-1 cyst is causing problems, it would likely be to your stomach or esophagus or digestive system. Look up TOS, Thoracic Outlet Syndrome.

In my experience, the muscle spasms needed gentle treatment. My PT used myofascial release to release the spasms. Over a year of treatment and my good discipline with posture, especially during sleep or napping, my neck is much better.

My neck interrupted blood flow to my brain during sleep causing me to have stressful dreams and a bad day the next day.
